To all whom it may concern:

Be it known that 1, JOHN HARRIS, a citizen of the United States, residing atLakewood, in the county of Cuyahoga and State of Ohio, have invented a certain new and useful Improvement in Gaseous Fuel, of which the following is a full, clear, and exact description. '7

This invention relates to gaseous fuel capable of use for the purpose of cutting and welding metals as well as for heating large plates or masses of metal for the shaping thereof.

It was originally proposed to mploy hydrogen alone as the combustible element in blow pipe gases, but pure hydrogen offers certain disadvantages, one of which is its great intensity of combustion which conce trates the flame into a very small space. A further disadvantage is that all parts of the flame are colorless, thus rendering it impos-' sible for any but the most skilled operative to adjust the flame with reference to the oxygen admitted, or to apply the same in proper position to the work performed.

It has been proposed to impregnate the hydrogen with certain hydrocarbons which by reason of their slower combustion should spread the flame more widely and which by 130 reason of their visible combustion should define the position of the reducing cone and thus assist both the adjustment of the gas supply and in the application of the flame to the work. However the admixture of bytages: first, the very low flame temperature which most of them produce which impedes the operation of the torch or blow pipe even when used in a mixture with hydrogen; and second, their complicated molecular structure, which necessitates a great preponderance of oxygen in order to consume the same.

The composition of the gas is substantially as follows: i a

This increase in heat units renders my gaseous fuel particularly useful in preheating large masses of metal, such as castings, since it compensates for the loss of heat due to the conductivity of'such masses.

Eyen at the lower limit (15%) the water gas will compensate, by reason of the increasein heat units over hydrogen alone, for loss of heat by conduction in metal of considerably greater mass than possessed, by the plates comprising a mixture of hydrogen with car- With Which blowpipes; are ordinarily =em- 'buretted Water ga s in: the Volumetric proporployed, While at its upper limit (50%) it tions of Will compensate for such loss in practically Per cent 5 "any m 'OfImelZaL -Hydrogen *1 85.130 50 Thls application 1s,'-1n some respects- :2, 15 to 50 continuation of' my application No. 250,637 fil d A t 20 191 In testlmony whereof, I hereunto affix my Having thus described my invention What Signature- 10 I claim is:,- r
